Hybrid tea rose plant named `Jacfetex`

ABSTRACT

Hybrid tea rose having yellow, edged in orange-pink flowers; attractive, long well shaped bud; long open flowers on long stems; good cut flower production; and glossy, dark green foliage.

The present invention relates to a new and distinct variety of roseplant of the hybrid tea class which was originated by me by crossing thevariety `JACyem,` U.S. Plant Pat. No. 9,329, with the variety KORbacol,U.S. Plant Pat. No. 8,617.

The primary objective of this breeding was to produce a new rose varietyhaving the long stems, long bud and large open flower of the femaleparent combined with the bright yellow flower, good cut rose productionand glossy foliage of the male parent. The objective was substantiallyachieved, along with other desirable improvements, as evidenced by thefollowing unique combination of characteristics that are outstanding inthe new variety and that distinguish it from its parents, as well asfrom all other varieties of which I am aware:

1. Novel, yellow, edged in orange-pink, flowers;

2. Long, well-shaped bud;

3. Large, open flower;

4. Long stems;

5. Good cut flower production;

6. Dark green, glossy foliage.

`JACfetex` is a novel colored greenhouse grown cut rose. Flowers producethis novel color under high summer light intensity and low winter lightintensity, where other conditions such as temperature and humidityremain substantially constant. This feature is important to cut roseproduction and is uncommon among todays commercial cut rose varietiesthat have a mix of yellow and red or pink on petal edges. `JACfetex`plants grown in a greenhouse in California produce 160-180 stems permeter, the stems averaging 22-26 inches in length.

Asexual reproduction of this new variety by budding, as performed atWasco, Calif., shows that the foregoing and all other characteristicsand distinctions come true to form and are established and transmittedthrough succeeding propagations.

The accompanying illustration shows typical specimens of the vegetativegrowth and flowers of this new variety in different stages ofdevelopment, depicted in color as nearly true as it is reasonablypossible to make the same in a color illustration of this character.

The following is a detailed description of my new rose cultivar withcolor descriptions using terminology in accordance with The RoyalHorticultural Society (London) Colour Chart, except where ordinarydictionary significance of color is indicated.

Parentage:

Seed parent.--JACyem (U.S. Plant Pat. No. 9,329).

Pollen Parent.--KORbacol (U.S. Plant Pat. No. 8,617).

Classification:

Botanical.--Rosa hybrida.

Commercial.--Hybrid Tea.

FLOWER

Observations made from specimens grown in a greenhouse environment atSomis, Calif. from January, 1996-August 1997.

Blooming habit: Continuous.

Bud:

Size.--One and three-quarter inches long when the petals start tounfurl.

Form.--The bud form is long, pointed ovoid.

Color.--When sepals first divide, bud color is Yellow Group 13B edged inRed Group 45C. When half blown, the upper sides of the petals are YellowGroup 13C edged in Red Group 45D; and the lower sides of the petals areYellow Group 13C with a faint edge of Red Group 45D.

Sepals.--Color: Green Group 138B. Surface texture: Covered in finehairs. There are three normally to heavily appendaged sepals. There aretwo unappendaged sepals with hairy edges.

Receptacle.--Color: Green Group 146C. Shape: Funnel. Size: Medium (3/8"long×5/16" wide). Surface: Smooth.

Peduncle.--Length: Short (2" to 21/2"). Surface: Smooth. Color: GreenGroup 137A. Strength: Stiff, erect.

Bloom:

Size.--Large. Average open size is 41/2" to 5".

Borne.--Singly.

Stems.--Long (22-26"), strong.

Form.--When first open: High centered. Permanence: Retains its form tothe end; outer petal edges curl back.

Petalage.--Number of petals under normal conditions: 25-30.

Color.--The upper sides of the petals are Yellow Group 13C with eachpetal edged in Red Group 45D. The reverse sides of the petals are YellowGroup 13C with a faint edge of Red Group 45D. The base of the petals issmall (1/8"×1/8"), intense Yellow Group 13A half moon at the point ofattachment. The major color on the upper side is Yellow Group 13C.

Variegations.--None.

Discoloration.--At the end of the first day: No change. At the end ofthe third day: Little change. On the plant, during day four and dayfive, as the flower opens, the Red Group 45D color expands on the upperpetal surface. By day seven, the yellow color fades to Yellow Group 13D.

Fragrance.--Moderate.

Petals:

Texture.--Thick, leathery.

Shape.--Round to slightly deltoid.

Form.--Tips slightly recurved, edges slightly quilled.

Arrangement.--Imbricated. Petaloids in the center are few.

Persistence.--Drop off cleanly.

Lastingness.--On the plant: Long (7-8 days). As a cut flower: Long(11-12 days).

Reproductive parts:

Anthers.--Size: Large. Quantity: Many. Color: Yellow. Arrangement:Regular around styles.

Filaments.--Color: Yellow.

Pollen.--Color: Gold yellow.

Styles.--Color: Reddish.

Stigmas.--Color: Greenish-white.

Plant:

Form.--Bush.

Growth.--Very vigorous; upright; branching; Height at six months in thegreenhouse in Somis, Calif. is over six feet. By regular cutting of cutflower stems it has been kept at this height.

Foliage.--Number of leaflets on normal mid-stem leaves: Five or seven.

Size.--Large. (7"×51/2").

Quantity.--Abundant.

Color.--New foliage: Upper and lower surface: Greyed-Red Group 178A. Oldfoliage: Upper surface: Green Group 139A. Lower surface: Green Group139C.

I claim:
 1. A new and distinct variety of rose plant of the hybrid teaclass, substantially as herein shown and described, characterizedparticularly as to novelty by novel yellow, edged in orange-pinkflowers; attractive long, well-shaped bud, large open flowers; longstems; good cut flower production; and glossy, dark green foliage.
